August 2018 In t ro d uc ti o n The National Statistics Postcode Lookup (NSPL) relates both current and terminated postcodes in the United Kingdom to a range of current statutory administrative, electoral, health and other statistical geographies via ‘best-fit’ allocation from 2011 Census Output Areas (OA). National Parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations – see Section 7 for further details. It helps support the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly. This User Guide contains information about the NSPL including: • directory content; • data currency; • latest news, including area changes; • the methodology for assigning areas to postcodes; • data format; • summary statistics; and • data quality and limitations. The NSPL reflects current and terminated postcodes using information supplied monthly by Royal Mail. In most instances, the NSPL relates postcodes (as at the third Friday of the month prior to each release) to geographic areas as at the end of the preceding year. The NSPL uses the Government Statistical Service (GSS) standard 9-character codes throughout. Lookup files linking these codes to statutory area names are included with the NSPL, in the 'Documents' folder. You are encouraged to adopt these standard names and codes, as they are the recognised standard for National Statistics. The NSPL is available to download (see Annex C) and the record specification at Annex B includes complete details of all available fields. 2. N ews 2.1 M er ge d S us ta i na bi l i t y an d Tr ans for ma ti o n Pa rt ne rs hi p s The August 2018 release of the NSPL includes the merged STPs of Durham, Darlington, Teesside, Hambleton, Richmondshire and Whitby (E54000045), Northumberland, Tyne and Wear and North Durham (E54000046) and West, North and East Cumbria (E54000047) to form the Cumbria and North East STP (E54000049). 2.2 Ca n ce r Al l i a nc e N a me Cha n ge Also included for the August 2018 release is the re-named Cancer Alliance of West Yorkshire and Harrogate (E56000003). 2.3 Ca n ce r Al l i a nc es / N a ti o nal Ca nce r Va n g ua rd a n d S us tai n a bi l i t y an d Tra ns fo rm a ti on P a r tn ers hi ps The May 2018 release of the NSPL included the Cancer Alliances / National Cancer Vanguard (CALNCV) and the Sustainability and Transformation Partnerships (STP). 2.4 For ma t Cha n g es – N a mes an d Co d es Fi l es From May 2018, the names and codes files that accompany each release of the ONSPD will be supplied in MS Excel (XLSX) and UTF8 Comma Separated Variable (CSV) format. The latter replaces the tab-delimited text (TXT) format as the latter does not support the accented characters in some geography names. Click here for further information. 2.5 Im p or ta n t N S P L Fi el d Cha n ges f ro m Fe br u ary 2 018 For the February 2018 release onwards, the NSPL will include the following field after CTY: • County electoral division (CED) Office for National Statistics 5 NSPL User Guide August 2018 Two other fields will also be changing: • • The 2012 Pan SHA field (HRO) will be updated to the NHS England (Regions) (NHSER) The GOR field will be renamed RGN to reflect the 2010 Regions (former GORs) The HRO field will still be available on the NHSPD. These changes are being made to maintain the manageability of the postcode directory file sizes. 2.6 N or th er n Ir el a n d I M D Cha n ges The NI Index of Multiple Deprivation (IMD) was updated in November 2017. These changes are included from February 2018 on the NSPL. 3.

Note: We do not have the capability to deal with detailed postcode queries relating to Scotland and Northern Ireland, but can pass them on to the appropriate government departments. 4. Pos tco d e Co u n ts a n d Cu rr en cy The NSPL contains postcodes within the United Kingdom, the Channel Islands and the Isle of Man. They are current to the 3rd Friday of the previous month and include both live and terminated postcodes. Table 1 shows the split between large and small users by country, and the change in the numbers of postcodes since the previous quarter (counts taken from the ONSPD). Table 2 shows the numbers of postcodes, postcode sectors and postcode districts by postcode area. Table 3 shows the numbers of postcodes assigned grid references by positional quality indicator, country and user type (counts taken from the ONSPD). Table 4 shows the numbers of terminated postcodes. 5. Geo g ra ph y U pd a t es o n th e N S P L The OA lookups that serve as inputs to each release of the NSPL are usually updated at the end of each year. Therefore, the February release of the NSPL will generally be the first to reflect any geography changes in the previous year. This release contains 2018 LAD, ward and LAU2 codes, and April 2018 CCG updates. 6. Fr e qu en tl y As ke d Q u es ti o ns (F A Q) Why are some postcodes not assigned to administrative and electoral areas? Office for National Statistics 6 NSPL User Guide - August 2018 This mainly applies to new postcodes, which are assigned grid references by ONS Geography using imputation techniques - see Sections 6 and 7. In some cases the imputation procedure cannot assign a grid reference and, because the NSPL processing system assigns postcodes to OAs using grid references, codes for the administrative and electoral areas cannot be derived. In time, the addresses in the new postcodes are surveyed by Ordnance Survey (OS), who then assign accurate grid references. Why are some postcodes assigned to the wrong administrative and electoral areas? - There are two reasons: 1. Imputation: Some postcodes are assigned to administrative and electoral areas using an imputed grid reference. Imputation is not an exact science and can cause postcodes to be wrongly assigned until more accurate information becomes available. Please inform ONS Geography Customer Services of any postcodes considered to be wrongly assigned. 2. Straddling: As the postal, OA and higher geographies do not map directly onto one another, addresses within a postcode often straddle boundaries. Postcodes are always assigned to single administrative and electoral areas via ‘best-fit’ allocation of OA whilst allocation of postcode to OA is based upon a single grid reference (which is the mean of all the addresses in the postcode, snapped to the address closest to the mean). This will inevitably lead to apparent wrong assignments, where addresses in a postcode fall in two administrative/electoral areas (see Section 6). Why don’t postcode areas follow administrative and electoral area boundaries? - Postcode areas are defined and used by Royal Mail for efficient mail delivery and have no relationship with administrative and electoral areas. Royal Mail requires a relatively stable geography in order to deliver its services, which the administrative and electoral area geography cannot provide. Why do some postcodes appear to move around? - There are three main reasons: 1. Update: As the grid reference allocation is updated from imputed to surveyed (see Section 6), so the allocation of one or more geographies may also change. 2. Drift: With demolition and new-build, the addresses that constitute a postcode may change. If this happens the centroid grid reference will also change, and the geography allocations will be updated accordingly. 3. Re-use: Royal Mail endeavour to never re-use a postcode, but under some circumstances a postcode may be terminated and then brought back into use in a different location. If this happens, the grid reference and geography allocations will change accordingly. Why have some allocations changed after August 2012 when the geographies haven’t changed? - As part of the 2011 Census Output Area maintenance, OAs had their population weighted centroids recalculated using the latest Census populations. As well as this there was also a change in centroid calculation from the mean average to the median average. This change in the population and methodology means that almost all OA population weighted centroids have moved from their original position. In a number of cases the new OA population weighted centroids now fall into different higher geographies. This causes the differences in the allocations after August 2012, even where the geographies haven’t changed. Office for National Statistics 7 NSPL User Guide 7. August 2018 Pos tco d e Co n te n t The NSPL contains both ‘live’ postcodes and postcodes which have been terminated by Royal Mail but not subsequently re-used (see Section 8). Postcode coverage is for the entire United Kingdom, the Channel Islands and the Isle of Man. The split between large and small users and country and the changes in the numbers of postcodes since the previous NSPL are shown in Table 1 of the Version Notes. The numbers of postcodes, postcode sectors and postcode districts by postcode areas are shown in Table 2 of the Version Notes. The NSPL contains fixed length 7- and 8-character postcode formats, and the variable length e-Gif (e-Government Interoperability Framework) standard postcode format. The latter allows for a single space between the two (outward and inward) parts of the postcode (see Annex A). 8. Gri dl i n k The postcode is a key piece of data that can provide a geo-spatial reference for many uses beyond the delivery of mail. In order to make full use of its potential, and to deliver improved consistency, a consortium of organisations was formed in 1999 to allow the specialist resources of each member to be pooled. The Gridlink Consortium consists of Royal Mail Group plc, OS (GB), National Records of Scotland (NRS), Northern Ireland Land and Property Services (LPS) and ONS. It was recognised that a core set of data within each Consortium member’s postcode products needed to be consistent and branded. The branding name is 'Gridlink' and the core data used in the NSPL are: • All current (i.e. ‘live’) UK unit postcodes (but ONS maintains postcodes terminated and not subsequently re-used by Royal Mail). • Grid references to 1 metre resolution. • Positional quality indicators for grid references. Each of the Gridlink Consortium members produces their postcode products based upon the core data. 9. Geo g ra phi c C oo rdi na tes Postcode coordinates on the NSPL are available in two formats – 1 metre resolution grid reference and decimal degrees latitude and longitude. The majority of grid references are derived from OS AddressBase that contains grid references for each address. Newly introduced postcodes initially have a grid reference that has been imputed by ONS Geography. In due course these are replaced by improved OS AddressBase grid references which use data supplied by OS field surveyors. Each grid reference is given a Positional Quality Indicator (PQI) to denote the accuracy of the grid reference, as follows: 1 - within the building of the matched address closest to the postcode mean, 2 - as for 1 above, except by visual inspection of Landline maps (Scotland only), 3 - approximate to within 50 metres, 4 - postcode unit mean (mean of matched addresses with the same postcode, but not snapped to an address), 5 - imputed by ONS, by reference to surrounding postcode grid references, 6 - postcode sector mean (mainly PO Boxes), 8 - terminated postcode, last known ONS grid reference used, Office for National Statistics 8 NSPL User Guide August 2018 9 - no coordinates available. The grid references provided for Northern Ireland postcodes are derived from the LPS 'Pointer' product and use the Irish National Grid system that covers all of Ireland and is independent of the British National Grid. The degrees latitude and longitude are calculated from the 1 metre grid reference by converting the easting and northing to numeric and then one point shapefile is created for GB using the 'BritishNatGrid' coordinate system and another for Northern Ireland using 'Ireland 1965.ING'. These files are then projected to GCS_WGS_1984, using an OSGB_1936_to_WGS_1984_Petroleum transformation for GB and a TM75_to_WGS_1984_2 transformation for NI. Latitude and longitude are then calculated from the resulting x and y co-ordinates. No geographic coordinates are provided for postcodes in the Channel Islands and the Isle of Man. 10 . As s i g nm en t of Pos tc o des t o Geo g ra phi es o n th e N S P L Postcodes are assigned to administrative, electoral and health areas by 'best-fit' allocation to OA using the population-weighted centroid grid reference for each OA plotted against a range of digital boundaries using a ‘point-in-polygon’ methodology. Postcodes are themselves plotted to OA boundaries using their centroid grid reference and the same point-in-polygon methodology. The exceptions are National Parks (these are exempt due to the nature of their boundaries) and Workplace Zones (these are exempt as they are not built from whole OAs) – postcodes are allocated to these on an 'exact-fit' basis using the same point-in-polygon methodology. 11 . PO Bo xes a n d N o n- ge og ra phi c Pos tco d es Non-geographic postcodes can either be special postcodes assigned to some large users of the postal service or PO Boxes that lie within a (pseudo) postcode district that does not form a discrete part of a post town. These will all have been assigned a grid reference, usually the local Royal Mail sorting office, and the majority have a PQI of 1 but some have been assigned a PQI of 6 (see Section 9). 12 . Ter mi na t e d Pos tco d e s Postcodes are frequently terminated by Royal Mail for various reasons but most commonly it is due to the demolition/re-development of buildings or to postcode reorganisations (see next section). Terminated postcodes are occasionally re-used by Royal Mail but not usually before an elapsed period of two or three years. In such circumstances, all terminated postcodes and their grid references are retained on the NSPL and a 'termination' date is added which provides a clear indication of a postcode’s status. Areal data assigned to terminated postcodes are updated prior to each release of the NSPL, so the directory contains current information linked to each record. If, and when, a postcode is subsequently re-used by Royal Mail the old grid reference and termination date are removed, thus deleting all reference to the former existence of the postcode from the NSPL. The new location of the postcode will initially have a grid reference imputed by ONS Geography, which will eventually be replaced by an improved one derived from OS AddressBase. As the Gridlink system processes only 'live' postcodes it is not possible to assign Gridlink quality grid references to postcodes terminated prior to November 2000. Grid references for these postcodes have been copied from the old 'Traditional' postcode directory and have been given a single PQI (value 8). The numbers of terminated postcodes included in each issue of the NSPL are shown in Table 4 of the Version Notes. Office for National Statistics 9 NSPL User Guide 13 . August 2018 Pos tco d e Reo r ga ni s a t i ons Royal Mail occasionally conduct postcode reorganisations in order to create more postcodes in areas where the number of postcodes that can be created under the current structure is exhausted. For example, SO3 was reorganised some years ago into SO31 and SO32 to cater for current demands, and the reorganisation additionally allows SO33-SO39 postcodes to be assigned at a later date. Royal Mail issue lists of postcode reorganisations in their 'Update' series, details of which can be found at their website. 14 . For m er S t ra te gi c H ea l th Au t ho ri ti es (S H A) , H eal t h Boa r ds a n d H eal th & S oci al Care Boa r d The maintenance of health area codes is the responsibility of the Organisation Data Services (ODS) in England, and ONS on behalf of NHS Scotland and Health Solutions Wales. These areas were reorganised in England in 2002, in Wales in 2003 and in Scotland in 2006. The SHAs in England were further reorganised by the NHS on 1 July 2006 to reduce the number from 28 to 10 before being abolished on 31 March 2013. In Northern Ireland the Health & Social Care Board effective from 1 April 2009 replaced the four previous Health & Social Services Boards. The following health authority codes apply to Channel Islands and the Isle of Man: L00000001 – Jersey L00000002 – Guernsey (incl. Sark and Herm) L00000003 – Alderney M00000001 – Isle of Man 15 . For m er Pri ma ry Ca re Or ga ni s a ti o ns ( P CO) , Lo cal H eal th Boa r ds ( LH B) , Com m uni ty H e a l t h Pa rt ne rs hi ps (CH P) an d Lo cal C om mi s s i o ni n g Gro u ps (L CG ) Postcodes on the NSPL have been assigned PCO codes (England), LHB codes (Wales), CHP codes (Scotland), LCG codes (NI) or Primary Healthcare Directorate code (Isle of Man). Postcodes in the Channel Islands (for which there are no equivalent areas) have been assigned a pseudo code. The primary care geography in England was reorganised significantly on 1 October 2006. When PCOs were statutorily defined, they were done so in terms of whole local authority districts and/or electoral wards (in most instances) that existed at the time. There were 146 Primary Care Trusts (PCT) and five Care Trusts in place when they were abolished on 31 March 2013. The 22 LHBs in Wales (from 1 April 2003) merged to form seven LHBs on 1 October 2009. CHPs were established by the NHS boards in Scotland as key building blocks in the modernisation of the NHS joint services. Managed jointly by local authorities and health boards, CHPs nested within council area boundaries but some crossed health board boundaries. In April 2012, the 36 CHPs became 34, covering the whole of Scotland. CHPs were terminated on 31 March 2015. Five LCGs were introduced in Northern Ireland on 1 April 2009. A single Primary Healthcare Directorate was introduced in the Isle of Man in 2008 to support the rollout of NHS systems. 16. Cou n ty El ec tor a l Di vi s i ons ( C ED) English county councils use county electoral divisions (CED) to elect councillors. These CEDs must be confined within district boundaries, but need not be based on whole electoral wards. The only exceptions are the Isles of Scilly and the Greater London Authority (GLA). CEDs do not exist within UAs. Office for National Statistics 10 NSPL User Guide 17 . August 2018 2011 Ce ns us Ou t p u t Ar ea s ( O A) 2001 Census OAs were built from clusters of adjacent unit postcodes but as they reflected the characteristics of the actual Census data they could not be generated until after data processing. They were designed to have similar population sizes and be as socially homogenous as possible (based on tenure of household and accommodation type) - note though that homogeneity was not used as a factor in Scotland. Urban/rural mixes were avoided where possible (i.e. OAs preferably consisted entirely of urban postcodes or entirely of rural postcodes). They had more-or-less regular shapes and tended to be constrained by obvious boundaries such as major roads. The OAs were required to have a specified minimum size to ensure the confidentiality of data. England and Wales OAs were maintained after the 2011 Census so that they could be adjusted where the populations had changed significantly. Where an OA had breached its upper threshold of 625 population or 250 households it was split down to create a number of smaller OAs. Where an OA had breached its lower threshold of 100 population or 40 households it was merged with an adjacent OA to create a geography that was within threshold. OAs created as part of the 2011 Census maintenance were based on postcodes as at Census Day 2011 while the unmaintained OAs reflected the postcodes as at Census Day 2001. The minimum OA size is 40 resident households and 100 resident persons but the recommended size was rather larger at 125 households. These size thresholds meant that unusually small wards and parishes were incorporated into larger OAs. In total there are 181,408 OAs in England (171,372) and Wales (10,036). National Statistics policy is that estimates published for any geographical area are aggregations of whole OAs (the lowest geographical level for which census estimates are produced). This policy ensures that estimates can be released for any area that contains at least one OA, in that it will contain the minimum population to ensure confidentiality. Eighteen wards have a very small population and have been assigned to a 'parent' OA (see Annex C for details). In 2003, OAs fitted within the boundaries of 2003 statistical wards (and parishes) but this relationship had not been maintained for 2011 due to the high levels of administrative geography boundary change. In 2003 postcodes that straddled an electoral ward/division (or parish) boundary were split between two or more OAs. This scenario is now more prevalent as the postcodes have changed during the intercensal period without this being reflected within the OA hierarchy. Scotland OAs for the 2011 Census were created as groups of postcodes nesting as well as possible into the following geographies, in descending order of preference (when not all postcodes in the OA belong to a single combination of these area types). - Council Area - The 2010 Locality dataset The main aim governing this order of geographies was to give continuity with the 2001 OAs while ensuring, as far as possible, that 2011 OAs fit into the appropriate locality (urban area) which are seen as an increasingly important statistical area. Where possible, postcodes that were excluded from the 2010 Locality dataset, but subsequently met the population density criteria for inclusion in a locality, were included in an OA in the locality or grouped to form a new urban OA. The majority of 2011 OAs are of similar size to those used in 2001 to allow as much comparison as possible with the 2001 Census data. Where a 2001 OA dropped below the 2011 minimum thresholds for confidentiality (50 persons and 20 households) e.g. because of housing demolitions, it was merged with a neighbouring 2001 OA. In addition, 2001 OAs which increased in size, particularly those which exceeded the 2011 recommended maximum threshold (approximately 78 households), were split where possible into two or more OAs. Office for National Statistics 11 NSPL User Guide August 2018 Northern Ireland Updated 2011 Census OAs are called small areas and are re-coded to nine-character format. There are 4,537 small areas in Northern Ireland. 18 . 2011 Ce ns us Ar ea Cl a s s i fi ca ti o n f or O ut p u t A reas (O A C) The 2011 Census OAC is used to group together geographic areas according to key characteristics common to the population in that grouping. These groupings are called clusters, and are derived using 2011 population census data. The classification was originally produced with lower case characters but these have been converted to upper case for consistency purposes on the NSPL. You can download a complete listing of the OAC names and codes from the Open Geography portal. 19 . 2011 Ce ns us S u per Ou t p u t Ar eas (S O A) & S co t ti s h Da ta an d I nt er me di at e Zo nes ( DZ & I Z) SOAs exist in England, Wales and Northern Ireland; the Scottish equivalents are DZs and IZs. England and Wales The Lower Layer SOAs (LSOA) were designed with a mean population figure of 1,500 and each consists of a grouping of OAs, typically five. There are 34,753 LSOAs, with an absolute minimum population size of 1,000. The Middle Layer SOAs (MSOA) have a mean population figure of 7,200 (minimum 5,000) and consist of a grouping of LSOAs. MSOAs are constrained by the 2003 local authority boundaries used for 2001 Census outputs. The LSOAs and MSOAs have been maintained as part of the 2011 Census OA maintenance. As with OAs, they have been split or merged where they have breached predefined population and household thresholds. Scotland DZs are groups of OAs which have populations of between 500 and 1,000 household residents. Redrawn as a result of detailed population information from the 2011 Census, they have been available since November 2014. IZs are the geography that sits above DZs and they have a minimum population of 2,500 - 6,000, which are of a size between the LSOAs and MSOAs in England and Wales. There are 1,279 IZs. Northern Ireland In Northern Ireland SOAs were released in 2005. There is one layer of SOA, with a population size between 1,300 and 2,800, similar in size to the LSOAs in England and Wales. 20 . W es t mi ns t er Pa rl i a m en ta ry C ons ti t ue nci es England and Wales Parliamentary constituencies relate to those defined by the Parliamentary Constituencies (England) Order 2007, the Parliamentary Constituencies (England) (Amendment) Order 2008 and the Parliamentary Constituencies (Wales) (Amendment) Order 2008, and which came into effect at the May 2010 General Election. No further changes are envisaged until 2020. Scotland The Scottish Parliament (Constituencies) Act 2004, passed by the UK parliament in July 2004, came into effect upon the dissolution of the last UK parliament and breaks the linkage between UK parliamentary constituencies and Scottish parliamentary constituencies. This Act has enabled the Westminster government to reduce the number of Scottish constituencies in the UK parliament in Office for National Statistics 12 NSPL User Guide August 2018 line with recommendations made by the Boundary Commission for Scotland following its Fifth Periodical Review of Constituencies (December 2004). The Parliamentary Constituencies (Scotland) Order 2005 details the reduction of the number of constituencies for the UK parliament from 72 to 59 Scottish seats. The changes bring the size of Scottish constituencies more into line with the size of English seats. English constituencies currently contain nearly 70,000 voters on average, compared to the Scottish average of 53,500. Northern Ireland In Northern Ireland the commission's Fifth Periodical Report on Parliamentary Constituencies outlined changes to and the composition of constituencies in 2010. In practice the new parliamentary constituencies are not very different to their predecessors. As before there are 18 constituencies, all retaining the same name. In the main, the boundary amendment process has involved the reassigning of existing electoral wards from one constituency into a neighbouring constituency. The only exception concerns Derryaghy ward within Lisburn City local government district which previously resided entirely within Lagan Valley county constituency. It has now been split into two separate wards - Derryaghy (North) and Derryaghy (South), the former now included in Belfast West borough constituency, the latter remaining where it was. 21 . Eu ro p ea n El ec to ra l R egi ons ( EE R) EERs are as defined in the European Parliamentary Elections Bill (Bill 65, 1997) to amend the European Parliamentary Elections Act 1978 so as to alter the method used in Great Britain for electing Members of the European Parliament. The Bill created 9 EERs in England with 64 MEPs; Scotland, Wales and Northern Ireland each constitute a single EER, with 7 MEPs, 4 MEPs and 3 MEPs respectively. 22 . N om en cl a tu re of U ni t s for T e rri to ri al S ta ti s ti cs (N UT S ) NUTS is a hierarchical classification of spatial units that provides a breakdown of the European Union’s territory for producing regional statistics that are comparable across the Union. The NUTS area classification in the United Kingdom comprises current national administrative and electoral areas, except in Scotland where some NUTS areas comprise whole and/or part Local Enterprise Regions. NUTS levels 1-3 are frozen for a minimum of three years and NUTS levels 4 and 5 are called local administrative units (LAU) levels 1 and 2 respectively. The NSPL contains the LAU2 code (9-character ward code for England and Wales, 'S31' code for Scotland and, currently, the 10-character Eurostat code for Northern Ireland). A comprehensive lookup of LAU and NUTS codes is included with the accompanying metadata. 23 . N HS E n gl a n d ( R e gi o n s ) ( N H S ER) NHSERs (formerly NHS Commissioning Regions - NHS CR) are sub-divisions of the NHS commissioning board. There are four NHS ERs in England and they were renamed from NHS CRs in May 2017. The NHS CRs were formed on 1 April 2013, replacing pan SHAs, and are responsible for providing clinical and professional leadership at sub-national level. They are also responsible for the co-ordination of planning, operational management and emergency preparedness at sub-national level and undertaking direct commissioning functions and processes. 24 . Re gi o ns ( F or me r Gov er nm e nt Of fi ce Re gi o ns - G OR) The nine GORs were abolished on 1 April 2011 and are now known as 'regions' for statistical purposes. They were the primary statistical subdivisions of England and also the areas in which the Office for National Statistics 13 NSPL User Guide August 2018 Government Offices for the Regions fulfilled their role. Each GOR covered a number of local authorities and will remain as a 'frozen' geography on the NSPL. 25 . Lo cal Lea r ni n g a n d S ki l l s C ou nci l ( L LS C) / D ep t . o f Chi l d re n , E du cati on , Li f el o n g Le ar ni ng a n d S ki l l s ( DC E L LS ) , E nt er p ri s e R egi ons ( ER) LLSCs were introduced in 2001, replacing TECs in England. They were abolished on 31 March 2010. Also in 2001, TECs in Wales were replaced by ELWas (Education and Learning Wales). In April 2007 DCELLS replaced ELWas. These organisations were established to increase the standards and range of learning opportunities for businesses, communities and the individual. There were 47 LLSCs in England and there are four DCELLS areas in Wales. ERs replaced LECs in Scotland after September 2007. Government-funded bodies, they aim to foster local economic growth and development in Scotland. 26 . Trav el to W or k Are a s ( T T W A) TTWAs are used in labour market analysis and reflect reasonably self-contained zones in which the bulk of the resident population also work. The 228 current TTWAs were defined in 2015 using 2011 Census information on home and work addresses and are built from 2011 Census LSOAs in England and Wales, DZs in Scotland, and SOAs in Northern Ireland. The previous (2007) areas were based on the same statistical geographies from the 2001 Census. 27 . N ati o na l Pa r ks National parks are designed to conserve the natural beauty and cultural heritage of areas of outstanding landscape value, and to promote public understanding and enjoyment of these areas. There are currently 13 national parks in England and Wales. Of these, 10 were designated in the 1950s following the National Parks and Access to the Countryside Act 1949, The Broads (Norfolk/Suffolk) has had a similar status since 1989 (the Broads has its own special authority, the Broads Authority, which is similar to the National Park Authorities but with extra powers in relation to navigation) and The New Forest was given national park status in 2005. The South Downs is the latest national park, becoming fully operational on 1 April 2011. In Scotland the National Parks (Scotland) Act was passed in July 2000. The first Scottish national park, Loch Lomond and the Trossachs, was established in July 2002, and the Cairngorms National Park was established in March 2003. Their boundaries are not constrained by any other geography. Unlike other geographies (apart from Workplace Zones – see next section), postcodes are assigned to a national park on an 'exact-fit' basis rather than 'best-fit'. 28 . 2011 Ce ns us Wo r k pl a ce Zo nes ( W Z) Following the 2011 Census, a new geography, WZ, was created for England and Wales, followed in due course by Scotland and Northern Ireland. These were produced based on workplace data collected from the Census. WZs are created by merging or splitting the 2011 OAs using WZ postcode building blocks, and because of this, postcodes are allocated to WZs on an 'exact-fit' basis rather than 'best-fit'. The upper threshold of a WZ is unlimited postcodes or 625 workers and the lower threshold is three postcodes or 200 workers. 29 . Cl i ni c a l C om mi s s i o ni n g Gro u ps (CC G) CCGs are groups of GPs that are responsible for designing local health services in England by commissioning or buying health and care services, and all GP practices have to belong to a CCG. They came into effect on 1 April 2013 and are built from 2011 LSOAs. Office for National Statistics 14 NSPL User Guide 30 . August 2018 2011 Ce ns us B ui l t- u p A rea s ( BU A)/ B ui l t- u p A rea S u b- di vi s i o ns (BU AS D) England and Wales BUAs and BUASDs were created as part of the 2011 Census outputs and provide information on villages, towns and cities, allowing comparisons between people living in built-up areas and those living elsewhere. Previously called urban areas, data has been produced every 10 years since 1981. A new methodology to capture the areas was used in the 2011 version, but it still follows the rules used in previous versions so that results will be broadly comparable. There are areas included in the ONSPD but not in the NSPL. These BUAs and BUASDs have been identified as areas that have not been allocated a population. In most cases this is because they do not have any residential buildings – for example, industrial estates, airports, theme parks, etc. There are 337 BUAs where population has not been allocated (305 in England, 32 in Wales) and 133 BUASDs where population has not been allocated (123 in England, 10 in Wales). Scotland This data is not yet available. Northern Ireland This data is not yet available. 31 . 2011 Ce ns us Ru ra l - Ur ba n Cl a s s i fi c ati on England and Wales The rural and urban classification of postcodes for England and Wales allows a rural/urban view of datasets. It is based on the 2011 rural-urban classification of OAs released in August 2013. This product was sponsored by a cross-Government working group comprising Department for Environment, Food and Rural Affairs (DEFRA), Department of the Communities and Local Government (DCLG), ONS and the Welsh Government. It is a revised version of the classification produced after the 2001 Census, but with additional detail in the urban domain. Postcodes have been assigned to the urban or rural category of the OA into which each one falls. OAs are treated as 'urban' if they were allocated to a 2011 built-up area with a population of 10,000 or more. The urban domain is then further sub-divided into three broad morphological types based on the predominant settlement component. As with the previous version of the classification, the remaining 'rural' OAs are grouped into three broad morphological types based on the predominant settlement component. The classification also categorises OAs based on context – i.e. whether the wider surrounding area of a given OA is sparsely populated or less sparsely populated. The resulting classification produces the following 10 classes (note, there are no major or minor conurbations in a sparse context): A1 = urban major conurbation: OA falls within a built-up area with a population of 10,000 or more and is assigned to the 'major conurbation' settlement category. The wider surrounding area is less sparsely populated; B1 = urban minor conurbation: OA falls within a built-up area with a population of 10,000 or more and is assigned to the 'minor conurbation' settlement category. The wider surrounding area is less sparsely populated; Office for National Statistics 15 NSPL User Guide August 2018 C1 = urban city and town: OA falls within a built-up area with a population of 10,000 or more and is assigned to the 'city and town' settlement category. The wider surrounding area is less sparsely populated; C2 = urban city and town in a sparse setting: OA falls within a built-up area with a population of 10,000 or more and is assigned to the 'city and town' settlement category. The wider surrounding area is sparsely populated; D1 = rural town and fringe: OA is assigned to the 'town and fringe' settlement category. The wider surrounding area is less sparsely populated; D2 = rural town and fringe in a sparse setting: OA is assigned to the 'town and fringe' settlement category. The wider surrounding area is sparsely populated; E1 = rural village: OA is assigned to the 'village' settlement category. The wider surrounding area is less sparsely populated; E2 = rural village in a sparse setting: OA is assigned to the 'village' settlement category. The wider surrounding area is sparsely populated; F1 = rural hamlet and isolated dwellings: OA is assigned to the 'hamlet and isolated dwelling' settlement category. The wider surrounding area is less sparsely populated; F2 = rural hamlet and isolated dwellings in a sparse setting: OA is assigned to the 'hamlet and isolated dwelling' settlement category. The wider surrounding area is sparsely populated. Scotland The rural-urban classification in Scotland is consistent with the Scottish Executive’s core definition of rurality that defines settlements of 3,000 or less people to be rural. It also classifies areas as remote based on drive times from settlements of 10,000 or more people. This definition is unchanged from the 2001 Census: 1 = Large Urban Area: Settlement of over 125,000 people; 2 = Other Urban Area: Settlement of 10,000 to 125,000 people; 3 = Accessible Small Town: Settlement of 3,000 to 10,000 people, within 30 minutes’ drive of a settlement of 10,000 or more; 4 = Remote Small Town: Settlement of 3,000 to 10,000 people, with a drive time of 30 to 60 minutes to a settlement of 10,000 or more; 5 = Very Remote Small Town: Settlement of 3,000 to 10,000 people, with a drive time of over 60 minutes to a settlement of 10,000 or more; 6 = Accessible Rural: Settlement of less than 3,000 people, within 30 minutes’ drive of a settlement of 10,000 or more; 7 = Remote Rural: Settlement of less than 3,000 people, with a drive time of 30 to 60 minutes to a settlement of 10,000 or more; 8 = Very Remote Rural: Settlement of less than 3,000 people, with a drive time of over 60 minutes to a settlement of 10,000 or more.

Lo cal E nt er p ri s e Pa rt ne rs hi ps ( LE P) LEPs are voluntary partnerships between local authorities and businesses in England set up in 2011 by the Department for Business, Innovation and Skills to help determine local economic priorities and lead economic growth and job creation within the local area. They carry out some of the functions previously carried out by the regional development agencies which were abolished in Office for National Statistics 16 NSPL User Guide August 2018 March 2012. To date there are 39 LEPs in operation, with some areas overlapping. Please see the 'Guide to Presenting Statistics for LEPs' document on the Open Geography portal for further details. 33 . Pol i c e For ce A rea s ( P F A) There are currently 43 PFAs in England and Wales (39 in England and 4 in Wales), with one each for Scotland and Northern Ireland. They each comprise one or more complete local authority. Please see the 'Guide to Presenting Statistics for Police Force Areas' document on the Open Geography portal for further details. 34 .

Scotland The 2016 Scottish equivalent (SIMD16), based on 2011 Census DZs, ranks each DZ from 1 (most deprived) to 6,976 (least deprived). See link for further information. Northern Ireland The 2017 NI equivalent based on 2001 SAs (unchanged for 2011) ranks each SA from 1 (most deprived) to 890 (least deprived. See link for further information. N.B. Each IMD is unique ONLY within each country, and therefore should not be used in isolation. 35 . Can ce r Al l i a nc es a n d th e N a ti o nal Ca nc er Va n g uar d ( C A LN C V) CALNCVs lead the local delivery of the Independent Cancer Taskforce’s ambitions for improving services, care and outcomes for everyone with cancer. There are currently three National Cancer Vanguard areas (one covering Greater Manchester and two covering London) and 16 Cancer Alliances covering the rest of England. 36 . S us tai na bi l i ty a n d T r a ns fo r ma ti o n Par t ne r s hi ps (S T P) There are 44 STPs covering all of England, where local NHS organisations and councils have drawn up proposals to improve health and care in the areas they serve. STP can also stand for ‘sustainability and transformation plan’ - plans drawn up in each of these areas setting out ways to improve NHS services and population health in England. 37 . N ames a n d C o des The names of all administrative and health areas are the standard names adopted for use throughout National Statistics. The names are those used in Acts of Parliament and Statutory Instruments to publish changes to the administrative and health geographies. The NSPL uses the Government Statistical Service (GSS) standard nine-character codes for administrative, electoral and health areas. You are encouraged to adopt these standard names and codes, as they are the recognised standard for National Statistics. You can download full names and codes listings from the Open Geography portal. 38 . Di r ec to ry S p eci fi ca ti ons Annex A lists the specification for the records on the NSPL, giving the length and description of each field, the range of possible codes and any qualifying comments. It also provides further general Office for National Statistics 17 NSPL User Guide August 2018 information on each field, such as source, currency and extent of data. For those customers using the .dbf or .csv formats, the field names are also given. 39 . Da ta Fo rm a t The NSPL is available to download in comma separated variable format. Details are given in Annex B. 40 . Li mi t ati ons / D a t a Q ua l i ty No warranty is given by ONS as to the accuracy or comprehensiveness of the data contained on the NSPL. We will take reasonable steps to correct any identified errors and, if appropriate, will re-issue the NSPL. Two types of errors may occur in the NSPL - omissions and inaccuracies. With such a large file it is inevitable that some information will be missing. With monthly postcode updating procedures the likelihood of missing postcodes is small. The very latest postcodes (i.e. those introduced between the latest monthly postcode update and the issue of the NSPL) will not be included, but any other missing postcodes are likely to have been absent from the Royal Mail data file which forms the basis of the monthly input into the NSPL. Missing postcodes should therefore be reported to ONS Geography Customer Services for forwarding to Royal Mail. As previously stated, inaccuracies also originate from two sources – straddling and wrong assignments (imputation). You should also note that the use of the NSPL to allocate individual addresses to geographies might be imprecise because of the effects of straddling and wrong assignments. If you identify any errors and/or omissions, you should notify ONS Geography Customer Services and, with the assistance of the appropriate Gridlink Consortium member organisation, we will endeavour to: - investigate all reports of suspected errors and/or omissions to areal references; and - inform you of the outcome within 5 working days if we can resolve the query ourselves. Corrections and identified omissions to the data content of the NSPL are included on the subsequent NSPL release. Incompatibility with certain spreadsheet packages Due to the large number of records on the NSPL, the standard CSV file is incompatible with certain standard spreadsheet packages. You should instead use the ‘multi-CSV’ file, which includes a file for each postcode area.
